PPG SigmaDur 540 is superior to other epoxy coatings in that it offers users a higher level of colour and gloss retention over a longer period of time and will not fade or wear out like other conventional paints.
PPG SigmaDur 540 can be applied simply by brush or roller to produce a highly decorative, durable finish in a variety of different RAL colours. SigmaDur 540 has a long pot life despite being quick drying. After 2 hours your surface will be dry to touch, reaching full cure after 7 days.
PPG SigmaDur 540 can be applied over all other epoxy coatings on almost any surface, vertical or horizontal, in interior or exterior environments. SigmaDur 540 is non yellowing so works well to resist the ongoing effects of UV light. SigmaDur 540 is part of the ISO 12944-6 System For Steel C4 High system.
